Abstract: This note estimates return periods of Atlantic basin hurricanes striking the continental United States. With Hurricane Katrina fresh on the public?s mind, there is considerable interest in this topic. The return periods ...

Abstract: This paper introduces a new distance metric that enables the clustering of general climatic time series. Clustering methods have been frequently used to partition a domain of interest into distinct climatic zones. However, ...

Abstract: his paper studies genetic algorithms as a means of estimating the number of changepoints and their locations in a climatic time series. Such methods bypass classic subsegmentation algorithms, which sometimes yield suboptimal ...

Abstract: Changepoints (inhomogeneities) are present in many climatic time series. Changepoints are physically plausible whenever a station location is moved, a recording instrument is changed, a new method of data collection is ...

Abstract: his paper examines multiple changepoint detection procedures that use station history (metadata) information. Metadata records are available for some climate time series; however, these records are notoriously incomplete ...

Abstract: limate time series often have artificial shifts induced by instrumentation changes, station relocations, observer changes, etc. Climate time series also often exhibit long-term trends. Much of the recent literature has ...

Abstract: his paper develops trend estimation techniques for monthly maximum and minimum temperature time series observed in the 48 conterminous United States over the last century. While most scientists concur that this region has ...

Abstract: This note updates the temperature trend study of the contiguous 48 United States by Lund et al. for data observed during the 4-yr period 1997?2000. A parsimonious changepoint parameterization is now used, and the methods ...

Abstract: igh-resolution satellite precipitation estimates, such as the Climate Prediction Center morphing technique (CMORPH), provide alternative sources of precipitation data for hydrological applications, especially in regions ...

Abstract: AbstractThis paper develops a method for homogenizing daily temperature series. While daily temperatures are statistically more complex than annual or monthly temperatures, techniques and computational methods have been ...
